2 nPartition Server Hardware Overview This chapter describes the cell-based HP server models, including system capacities, model strings, and differences among the cell-based server models. Both HP 9000 servers and HP Integrity servers are discussed here. • The HP 9000 series of servers has HP PA-RISC processors. The cell-based HP 9000 servers include three generations of servers: the first-generation models, models based on the HP sx1000 chipset, and models based on the HP sx2000 chipset. • The HP Integrity series of servers has Intel® Itanium® 2 processors. The cell-based HP Integrity servers either are based on the HP sx1000 chipset or are based on the HP sx2000 chipset. sx1000 Chipset for HP Servers The second generation of cell-based servers is built around the HP sx1000 chipset. The sx1000 chipset supports both single-core and dual-core processors, including both HP PA-RISC and Intel® Itanium® 2 processors. The following servers use the HP sx1000 chipset: • PA-RISC servers - HP rp7420, HP rp8420, HP 9000 Superdome (SD16A, SD32A, and SD64A models). • Itanium® 2-based servers - HP rx7620, HP rx7620-16, HP rx8620, HP rx8620-32, HP Integrity Superdome (SD16A, SD32A, SD64A models). The HP sx1000 chipset provides a scalable server architecture with high-bandwidth processor, memory, and I/O busses. The HP sx1000 chipset includes interconnecting components such as memory buffers, I/O bus adapters and host bridges, and cell controllers, which have built-in low-level error correction. One notable administration feature of HP servers built around the HP sx1000 chipset is management processor (MP) support for access to the server using IPMI over LAN. For details see "Remote and Local Management of nPartitions" (page 41). sx2000 Chipset for HP Servers The third generation of cell-based HP servers is built around the HP sx2000 chipset. The following servers use the HP sx2000 chipset: • PA-RISC servers - HP rp7440, HP rp8440, HP 9000 Superdome (SD16B, SD32B, SD64B models). • Itanium® 2-based servers - HP rx7640, HP rx8640, HP Integrity Superdome (SD16B, SD32B, SD64B models). The HP sx2000 chipset provides a scalable server architecture with high-bandwidth processor, memory, and I/O busses. The HP sx2000 chipset includes new cell boards with core I/O, new system and I/O backplanes, new interconneting components, and the addition of a redundant clock source that is hot-swappable. HP servers built around the HP sx2000 chipset include management processor (MP) support for access to the server using IPMI over LAN. For details see "Remote and Local Management of nPartitions" (page 41).
